P38A Tailgate wouldnt open.

MrGorsky · Feb 13, 2025

EDIT! The lock actuator does earth through the CDL switch and the driver door ourtstation. That's just so it knows it's locked though don't you think? Rather than just ajar.

There is a tailgate switch though.... and that earths at the RHS tailgate lights. A good clean of all those contacts would probably help everything. Nothing I can see about the drivers door ajar microswitch though.

I said "like", the lower wont open if it thinks the top is closed.

I have got a lazy microswitch for the interior lamp drivers side, takes ages for the lamp to come on when it's cold outside, quicker or instant when it's warm. Does that particular micro switch just provide the earth for the tailgate latch and it doesn't trigger anything else?

To be honest I don't know. Electrikery is my weaker point

There is no electrickery, first press releases the upper tailgate, second press releases the lower tailgate, it's all mechanical.

I have an alternative to the OEM tailgate button that doesn't freeze up and costs a fraction of the price. Looks just like OEM unless you have the chrome button.

Data did a post about that so yes.

Maybe take the cover off the inner lower tailgate incase And take a big cuppa for a good looking at.

That's given me a thought...the hole I made in the card allows me to open the lower hatch with my finger or a screwdriver but I've never checked to see if it would also release the top hatch as that has never failed to open (until yesterday).
I shall fiddle somewhat tomorrow if its not too cold or rainy or windy or something.

So.
If I press it once then push on the upper (closing it) then push again why does it open the top again first?

I don’t know but there has to be away of knowing the top is open.

As far as I can see. it's purely mechanical. When the top latch is undone, the mechanism will unlock the lower latch.
If you re-close the upper tailgate, the latch is in the closed position so if the button is pressed again, it's the upper tailgate that will open again not the lower.

Ok I can agree.
Maybe the solenoid has a spring “to unlatch” so it will pull 1 then 1 again (does that make sense?). Or a ratchet that resets 2 clicks
But how does the tailgate open warning work?

I don’t know am not about to go looking this time of night

Never looked at the operation of the tailgate open warning but it will be from the upper tailgate latch mechanism.

Maybe micro switches?

Mark Piercy · Feb 13, 2025

Maybe once the top section is open the latch switches the current via the lower gate locking mechanism.. It kind of makes sense...

There is only one release solenoid.

But I thought it was only a “buckle” in the upper tailgate.
All the gubbins is in the lower.
